Degrees Minutes & Seconds. 360 ° in a circle 1° = 1/360 of a circle 1’ = 1/60 of one degree 1” = 1/60 of one minute 1° = 60 minutes or 3600 seconds. Adding DMS. Examples 25° 22’ 15” + 60° 15’ 49” 85° 37’ 64” or 85° 38’ 04” 55° 55’ 43” + 67° 43’ 29”

Review: (All odd textbook answers are in the back of the book.) 1. Convert decimal degrees to DMS and visa versa (2 decimal places) (See DMS “Convert” section of the Handout, work Column 3). 2. Convert degrees to π radians. (p 261 # 3(a-d))
